Hot air balloons generally descend at the rate of 200 to 400 ft./min. Six balloons to send 245 ft./min. For four minutes find the total change of the outlet today for all six balloons

1,715 feets

Step-by-step explanation:

Give the following :

General descent rate of hot air balloon = 200 - 400ft/min

Six balloons descend at a rate of 245 ft/min for four minutes

The total change in altitude for all six balloons :

From speed = distance / time

Speed = 245 ft / min ; time = 7 minutes

Hence distance descended by the six balloons :

245 ft/min × 7 minutes = 1,715 fts

Hence total change in altitude = 1,715 feets
